Where:
On any road, particularly in rural areas, near farms, orchards, or fields where tractors, harvesters, and other slow-moving agricultural machinery are commonly used.

Purpose:
To warn drivers that tractors or other slow-moving agricultural vehicles may be crossing, entering, or traveling along the road ahead.
These vehicles move much slower than regular traffic and may require extra space to turn or maneuver, creating potential hazards for faster-moving vehicles.

Action:
Slow down and stay alert for any agricultural vehicles on or near the road.
Allow sufficient space when approaching, passing, or following these vehicles, as they may move unpredictably or turn onto the road suddenly.
Be patient and only overtake when it is safe and legal to do so, ensuring that there is clear visibility and no oncoming traffic.
Always anticipate the possibility of sudden stops or wide turns.
